A Pool Is a 30-Year Structure — Vet Accordingly
Before you sign anything, ask direct questions and expect direct answers. A qualified California pool contractor won't hesitate on any of these — hesitation or a vague answer is itself useful information.
- What is your CSLB license number and classification, and is it currently active?
- Will you pull all permits in your company's name, or am I expected to as an 'owner-builder'?
- Can I visit two or three completed pools you've built within the last year?
- What is the exact rebar spec and shotcrete PSI for my pool shell?
- Are equipment brands and model numbers written into the contract, not just described generically?
- Who is my on-site superintendent, and how often will they actually be on-site?
- What is your typical change-order rate, and why do change orders happen on your jobs?
- What warranty covers the shell, plaster, tile, and equipment — and for how long, in writing?
- Who manages plaster startup and the water chemistry program in the first 28 days?
- What is the payment schedule, and does it comply with California's deposit cap?
- Do you carry active workers' comp and general liability insurance, and can I see certificates?
- Is my quote based on exact quantities and specified materials, or is it a rough allowance?
Why Question 12 Matters More Than People Realize
A quote built on exact quantities — real square footage, real linear footage, named materials — behaves very differently once construction starts than a rough allowance-based estimate. Allowance-based bids are where change orders come from, because the contractor never actually measured or specified what they were pricing. This is one of the four things we build every quote around at Moda: transparent pricing, exact quantities, sourced materials, and an extended warranty.
Red Flags to Watch For
- Bids 30% or more below the market range with no explanation for the gap
- Reluctance to name specific completed projects you can visit
- Payment terms that exceed California's deposit cap (10% or $1,000, whichever is less)
- Pressure to sign the same day for a 'discount'
- No mention of geotechnical or structural engineering on a sloped or hillside lot
💡 Pro Tip
Get three bids, not five. One bid gives you no comparison, five wastes everyone's time — three lets you compare scope of work line by line.
Verify Everything Independently
Don't take a license number at face value — verify it directly at cslb.ca.gov before you sign anything. It takes under a minute and immediately rules out a large share of unqualified bidders. Once you've narrowed to a shortlist, our free estimate tool is a good way to sanity-check the numbers you're being quoted.
Frequently Asked Questions
What's the single most important question to ask a pool contractor?
Whether the quote is based on exact quantities and named materials or a rough allowance — allowance-based quotes are the most common source of mid-project change orders.
How many bids should I get for a pool project?
Three bids is the sweet spot — enough to compare scope of work meaningfully without wasting time collecting bids you'll never use.
Should a pool contractor let me visit past projects?
Yes, a legitimate contractor should be able to arrange visits to two or three completed projects from the past year without hesitation.
What license does a pool contractor need in California?
A CSLB C-53 (Swimming Pool) classification, or a B (General Building) license with a qualifying C-53 individual on staff for the pool-specific work.
How do California's deposit rules protect me?
California law caps contractor deposits at 10% of the contract price or $1,000, whichever is less — any contractor asking for more upfront is violating state law.
